Application filed, rTune T0 all 107mm t muy @meer Be it lrnoivn that l,JOHN Fn'ersnvosn a citizen ot the United States, anda resi dent ot'Stamford, in the county oi? .i :held and State ot Connecticut, havevented certain neiv and usetul lniprovements in lioelrs; and l do herebydeclare the 'li'ollovving to be a full, clear, and enact description oitthe invention, such as Will enable others skilled in the art to which itappertains to maire and use the. same.

rllhis invention relates to improvements in locks and moreparticulaii'ly to such es may :be used for doors and the lilrelfoneobject ot my present invention being to proH vide o lock having aplurality otbolts adepted to have such interlocking connection ivith thestrike or keeper as to prevent separation of the lock casing and thekeeper or other- Wise j aicking of the lock With the use oit a jimmy orother burglars tool, and to so construct the loclr that the bolts willproperly and etiectuelly interlock with the -lieejl Without necessity`for causing the lock casin to project beyond the edge of the door.

Vi7ith this and other objects in view,n the invention consists incertain novel tentures of construction and combinations ot parts ashereinafter set forth and pointed out in the claim. Y i

ln the `accoinpanying drawings; Figure l is a longitudinal sectionalview ot a look embodying my improvements; Figure 2 .is a rear face viewWith cover plate ot the casing removed; Figure 3 is un edge vievv oitthe main bolt structure; Figure l is a tace view of said main boltstructure; Figure 5 is en edge view of the auxiliary or deadiloclringbolt structure; Figure G is a tace view ont the structure shown inFigure 5; Figi-ire 7 is a sectional vieiv partly in elevation shoviingthe bolts in retracted positions, with certain partsY ot the operatingmechanism omitted;` Figure 8 is a transverse sectional view of thestructure shown in Figure 7 with the bolts projected, but omitting thekeeper and showing the spring for the tumbler 28, and Figure 9 is a viewsimilar to Figure 7, but omitting the keeper and showing the boltsprojected.

In the drawings l have represented my improvements with a loclr of therim type, but it will be understood `that said improvements might beembodied in locks of other types. The easing l ot the lock may 1922..Serial No. 565,33L

be secured in any suitable manner to e door so that one end thereof Willlie flush with the vertical Jfree edge ot said door, and the lreeper 2may be secured to the door trame or joinb so as to be tlush or inalignment With the inner tace ot said jami. The Vieeper 2 is provided atits open side with lugs or cross members 3, 8, which are so spaced apartand trom the upper and lower walls ol" the keeper as to provide openings5j 6, tor the passing into the keeper oli bolt members carried by thelock casing es more fully hereinafter described. i

rlChe main bolt 7 ot the lock comprises a plurality ot bolt members 8, 9and l() carried by und integral with a body or apron member il mountedto slide on Ways 12 Within the casing. The body portion ot the mein boltcarries a talon 13 to be engaged by one or another pin lll carried by ecross head l5 secured to the spindle 16 of a knob 17, for projecting orwithdrawing the bolt. rlhe lrnob spindle and cross head may be held inthe position to which the same may be turned by rictionel engagement ofspring arms 18 .vith said spindle as indicated in Figure 2.

The members 8 and 9 of the main bolt structure are made hollow as shoivnin Figures l', 8 and 9 and es indicated by dotted lines in Figures l toil, and the top Wall et the intermediate bolt member 9 is provided withan opening 19, While the lower bolt Vmember l0 is provided with a socket20.

ylhe tree ends ot the several members S, 9, l@ ot 'the main bolt lieflush with the end ot the casing l when the main bolt is in Withdrawnposition and said end ot theI casing is provided` with e plurality otopenings tor the passage ot seid bolt members,

in auxiliary or dead locking' bolt structure 2l, shown separately inFigures 5 und 6 ot the drawings is carried by the main bolt structureand is movable transversely With relation thereto. The auxiliary boltstructure comprises a body portion 22 so asso-` ciated 'with the body orapron portion ll ot the main bolt structure as to be `movabletransversely of the and `urms 23`n` 2li movable in the hollow main boltmembers and provided With integral bolt members 25a 26. located inalignment with each other and both projecting in the same direction. Theconstruction. is such that When the main bolt is projected into thekeeper, the auxiliary bolt members 25, 26 will be caused to becomedisposed across the spaces between the main bolt members 8, 91 lO andbehind the lugs or cross members 8 ot the keeper-, the tree end of theauxiliary bolt member 25 entering` the hole 19 or the main bolt member 9and the free end of the auxiliary bolt member 26 entering the socket 20in the main bolt member l0. lV hen the main bolt is in withdrawnposition, the arms 23-24 and the bolt members 25-26 of the auxiliarybolt structure will be housed or enclosed within the hollow members 8-9ot' thn main bolt structure as shown in Figure 7.

The body portion 22 of the auxiliary bolt structure is provided with atalon 27 with which one or the other el: the pins la oi the cross head15 is adapted to cooperate to slide said auxiliary bolt stru-#turetransversely of the main bolt structure atter the main bolts shall. havebeen projected or withdrawn.

The talon 2T ot' the auxiliary bolt structure carries a tumbler 28having' a lugay 29 to travel in a slot 29n in the main bolt structurewhen the auxiliary bolt structure is moved transversely of said mainbolt structures. A spring' 80 serves to press the tu abler 2S rearwardlyso as to cause its lug` to enter an enlarged portion 3l at one end orthe other of the slot 29 and thus lock the auxiliary bolt structure inits projected position shown in Figures 2, 8 and 9, or in its retractedposition with the arms 2B. 24 and bolt mem bers 25, 26 housed in themain bolt members 8 and 9 when the bolts are in retracted positionswithin the casino'7 as shown in Figure 7.

I have hereinbe'lfore described knob operated means for controlling` theoperation of the lock, but it will be understood that key operated meansmay be provided also to operate the look trom the outside ot the door.ln Figure l of the drawing. l have indicated a roll bark cam 32 carriedby the cover plate 3?, oi the casingv tor cooperation with the bolts andthis cam majY be operated bj.' any suitable cylinder lock or other keyoperated construction not shown, as will be readily understood.

Then the bolts 7 and 2l are in locked relation to the keeper as shown inFigure 2. they may be retracted by operation ot the knob in thefollowingr manner: lVhen the knob spindle is turned to cause movement otthe pin il at the lower end cam or cross head l5 in the directionindicated by the arrow, said pin will operate first to depress thetumble-r and move its lug 29 out ot locked connection with the main bolt7 and enter the talon 27. As said pin continues to move upwardly itwill7 by cooperation with said talon, cause the auxiliary bolt structureto be moved upwardly to withdraw the auxiliary bolt members 25` 26 intothe hollow main bolt members 8, 9 and during such upv-.fard movement otthe auxiliary bolt structure, the lug 29 of the tumbler 28 will passupwardly through the slot 29l and when the auxiliary bolt member 25, 26shall have been fully retracted into the main bolt members 8, 9, tl etumbler lug 29 will snap into the enlarged upper end portion lll olEsaid slot and thus lock the auxiliair-y bolt members in such retractedpositions. As the operating` pin 14 continues to move in the are ot acircleg it will engage the talon l?) on the main bolt structure andretract the latter and the auxiliary bolt structure earried thereby7into the lock easing.

Slight changes might be made in the details ot construction ot myinvention without departing from the spirit thereof or limiting itsscope as defined by the appended claim and hence l do not wish lorestrict myselin to the precise details herein set forth.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent, is

ln a lock structure, the combination with a lock easing and a keeper, eta main bolt struct-ure mounted in the casing. an auxiliary boltstructure carried by the main bolt structure and movable transversely oithe latter, said auxiliary bolt structure having bolt membei havinginterlocking' cooperation with the keeper` a spring-pressed tumblercarried by the auxiliary bolt structure and cooperable with the mainbolt structure to lock the auxiliary bolt structure either in retractedor projected position relatively to the main bolt structure, manuallyoperable means cooperable with said tumbler to nnlock the auxiliary boltstructure Vfrom the main bolt structure and ttor moving said auxiliarybolt structure to projected orretracted position1 and means ooperablewith said manually operable means whereby operation of vthe latter willproject or retract the main bolt structure and auxiliary bolt structurerelatively to the lock casina and keeper.

ln testimony whereof, l have signed this specification in the presenceoft two subscribing' witnesses.
